Corporations, most LLCs, and all businesses with employees must have this IRS-issued identifier.

Much like a Social Security Number, an Employer Identification Number (EIN) is a federal nine-digit number that identifies a business entity. The Internal Revenue Service (IRS) issues EINs and requires their use on all tax filings during the entire life of a business.

The IRS generally requires the following types of businesses to obtain an EIN:

Any business that hires employees, including sole proprietorships and single-member LLCs

Many nonprofit organizations, as well as trusts and certain co-ops, must also have an EIN. If a business has changed its formation type or emerged from bankruptcy, it is typically required to apply for a new Employer Identification Number (EIN).

For many business owners, obtaining an EIN is one of the first things they do after incorporating or forming an LLC. Along with tax filings, businesses often need an EIN in order to:

open business checking accounts

establish accounts with certain vendors

Sometimes you'll see the Employer Identification Number referred to as a Federal Tax Identification Number (TIN) or a Federal Employer Identification Number (FEIN). As a general rule, it's good for all businesses, with the exception of sole proprietorships without employees, to have an EIN.

Similar to an individual's Social Security Number, a federal Employer Identification Number (EIN) identifies a business for tax purposes. Also called a Federal Tax ID, the EIN is issued by the Internal Revenue Service (IRS).

The IRS requires corporations, Limited Liability Companies (LLCs) operating as partnerships, and all employers to obtain an EIN. This number is used for all tax filings the business makes. Banks, lenders, and business partners may also request your EIN.

The IRS usually requires corporations and Limited Liability Companies (LLCs) operating as partnerships to obtain an EIN. Any business that hires employees, including sole proprietorships and single-member LLCs, must also apply for an EIN.

Banks may require an EIN in order to open a business checking account. Also, you may need to list your EIN on business license, permit, and tax registration applications.

If you misplaced an EIN previously issued by the Internal Revenue Service, you can either locate your copy of the IRS confirmation letter or web printout containing your EIN that the IRS issued after receiving your EIN application, or you can call the IRS at 800-829-4933. Make sure you have authority to request this information from the IRS. If you do not, the IRS will mail a confirmation letter containing the EIN to the taxpayer listed on the original application.
